CLOCK-PENDULUM.

SPECIFICATION forming part of Letters Patent NO. 404,997, dated June 11,1889.

Application iiled October 10, 1888. Serial No. 287,778. (No model.)Patented in Germany February l5, 1888, No. 44,446.

T all whom it may concern:

Be it known that I, JOSEPH \VERNER,f the city of Dresden, in the Kingdomof Saxony, German Empire, have invented certain new and usefulImprovements in the Means for Suspension of Pendulums of Clocks, (forwhich I have obtained a patent in Germany, dated February l5, 1888, No.44,446,) of which the following is a speciiicaticn, reference being hadto the accompanying drawings.

It is an essential point in clocks to construct -the mechanical parts otthe clockwork in such a manner that they'not only work with the leastpossible friction, but also so that bearings causing friction shall beavoided as much as possible, in order that variations in the resistanceof such frictional parts will be reduced as far as possible and theclock' may work regularly. The defects mentioned will mostly occur inthe means of suspending the pendulum. Such defects may be in some degreecounterbalanced by increasing` the weight; but the irregularities whichresult from'the above-mentioned defects in the bearings cannot beobviated thereby. Now, in order to obtain a suspension of the pendulum,causing the least possible friction, but at the same time allowing anexact adjustment of the hooking and of the stroke or swing of thependulum, I construct and combine the suspension devices, as hereinafterdescribed, and illustrated in the accompanying drawings, in which-Figure 1 represents a back view of a clock having my invention appliedto it. Fig. 2 represents a central vertical section of the same. Fig. 3is a view corresponding with Fig. 2, but on a larger scale, representingonly the parts included in my improvement. Fig. 4 is a top View of theanchor-spindle. Fig. 5 is a view at right angles to Fig. 8, partly insection in the line 0 0, of the escape-wheel and anchor, representing,also in section, the means of supporting the anchorspindle. Fig. 6represents a horizontal section in the line 5c :t of Figs. 8 and 5. Fig.7 represents a horizontal section in the line y y of Figs. 3 and 5.

Similar letters of reference designate corresponding parts in theseveral figures.

In the upper part of the clock-work I arrange a carrier A, (representedas a horizontal ban) for carrying the two swing-springs or flexiblesuspension parts D, which are connected together bythe anchor-spindle B.On the one end of said anchor-spindle B there is a head l), providedwith the carrying-pin a, on which the pendulum is suspended or hooked.

The carrier A is represented as adjustable 6o in height by means of ascrew d in the top of the clock-case, so as to be able to exactlyregulate the engagement of the anchor E into the balance-wheel orescapement-wheel. Furthermore, a guiding-pin c and a setscrew f areapplied between the carrier and the top of the case, so that no sidewiseshifting or displacement of the carrier A may take place. The hook ofthe pendulum-rod P is not affixed to the latter, but to the ad- 7ojusting mechanism, which is of peculiar construction, its principal partconsisting of the double-armed lever F, which may be turned or moved onthe fulcrum or pin g, provided on the rod P of the pendulum. This pin gconstitutes a pivotal suspension of the pendulum from the lever F. Theadjustment of said lever F is effected by means of the horizontal screw71, capable of turning in bearings afixed to the pendulum-stem, saidscrew 8o carrying a nut t, on which is a pin 7c, which enters betweentwo pins or a forkl on the lower end of the lever F. By turning thescrew h the nut t is shifted, and by means of the pins or fork Z thelever F and the 85.

pendulum are laterally adjusted the one to the other, and t-hependulum-rod is adjusted relatively to the center of suspension at a mto one side or the other, as may be rcquired.

Vhat I claim as my invention is- The combination, with thevertically-adjustablecarrier A, the anchor-spindle B, and thesuspension-springs D, suspending the said spindle from said carrier, ofthe adjust- 95 ing-lever F, suspended at its upper end from the@nehm-Spindle, the pendulum pivotully suspended from seid level.`between the ends of the laitier, and also connected with the lutter atthe lower end thereof, and the adjusting-serew 7l, applied al: thelast-mentioned eonneebion 'foi the lateral adjustment of Jelle pendulum,Substantially as herein described.

In testimony that I claim the 'foregoing' as my invention I have signedmy nume in presi ence of two subscribing; witnesses.
